This application is a continuation of U.S. application Ser. No. 11/277,682 filed Mar. 28, 2006 entitled “DOCUMENT PROCESSOR AND RE-AGGREGATOR”

BACKGROUND

An increasing number of mobile devices, such as cell phones and pocket PCs, are giving users the ability to read and edit documents. However, the ability to read and edit these documents is constrained by the limited screen size available on the mobile device. Furthermore, downloading a large document that may include graphs, images, embedded audio and/or video is a challenge. Not only may it take a long time to download a large document but the download may also be constrained by the storage limitations of the mobile device.

SUMMARY

The following presents a simplified summary of the disclosure in order to provide a basic understanding to the reader. This summary is not an extensive overview of the disclosure and it does not identify key/critical elements of the invention or delineate the scope of the invention. Its sole purpose is to present some concepts disclosed herein in a simplified form as a prelude to the more detailed description that is presented later.

Described herein are various technologies and techniques directed to methods and systems for a document processor and re-aggregator. In accordance with one implementation of the described technologies, a document is divided into one or more sections and formatting is removed. A condensed document is generated that includes one or more links to the one or more sections. The condensed document is transmitted to a mobile device to be displayed for a user. The user may choose to download one or more of the sections by selecting one or more of the links. Once downloaded, a section may be modified by the user. The modified section may then be transmitted from the mobile device. The modified section may then be re-aggregated with the unmodified sections to form a revised document.

DETAILED DESCRIPTION

The detailed description provided below in connection with the appended drawings is intended as a description of the present examples and is not intended to represent the only forms in which the present example may be constructed or utilized. The description sets forth the functions of the example and the sequence of steps for constructing and operating the example. However, the same or equivalent functions and sequences may be accomplished by different examples.

FIG. 1 is a block diagram illustrating an exemplary system 100 for implementing a document processor and re-aggregator. System 100 includes a server 120 communicatively coupled to a mobile device 102 and a computing device 130. Mobile device 102 includes a processor 104, a graphical user interface 106, storage 108, a transmitter 110, and a receiver 112. A document may be created by a user on the computing device 130. The document is divided into one or more sections. For example, the document may be divided based on the headers, pages, paragraphs, a table of contents, or via any other identifiable unit in the document. Each section may be given a unique number and version. Formatting may be removed from the document. For example, special fonts, paragraph formatting, and other types of formatting may be removed. The original formatting may be saved and used in the re-aggregation process. The original document may also be saved as an original version.

A condensed document is generated from the original document. The condensed document includes links to each of the sections of the original document. For example, if the original document was divided into sections based on the headers in the document, then the condensed document would include a link to each header, and each link would specify the name of the corresponding header. Each link may also specify one or more words in the corresponding section. For example, if the document is divided into sections based on paragraphs, then each link may specify one or more words that begin each corresponding paragraph. Each link may also indicate the file size of the corresponding section.

When there are items in the original document other than text, then a link may be included in the condensed document for each of these items. For example, a link may be included for a table, graph, image, audio, or video. Each link may also indicate the file size of the corresponding item.

After the condensed document is generated, the condensed document may be sent to a mobile device, such as 102. The mobile device 102 may display the condensed document for a user. The user may choose to download a section of the document by selecting the corresponding link. The file size of the section may be indicated in the link to let the user know approximately how big the section is and how long it may take to download the section. The user may also choose to download a table, graph, image, audio, video, or any other item within the document by selecting the corresponding link. The user may choose to download one section or item, may choose to download multiple sections or items, or may choose to download the entire document at once.

After a section is downloaded, the mobile device may display the section for the user. The user may then modify the section. The user may then choose to send the modified document back to the creator of the original document. The modified document may then be transmitted from the mobile device 102. The server 120 receives the modified document and compares each section of the modified document to each section of the original document. If there are changes to a section, then the modified section received from the mobile device is used to replace the original section. After all sections of the document are compared and any modified sections replaced, the server 120 re-aggregates the document. The previously removed formatting may then be added back into the document. The re-aggregated document may be saved as a revised version of the original document. The re-aggregated document may then be sent to the computing device 130. The re-aggregated document may then be displayed for the creator of the original document. Since the original version of the document was saved previously, after viewing the re-aggregated document, the creator of the original document may choose to revert to the original version of the document.

FIGS. 2-3 are flow diagrams illustrating exemplary processes for document processing and re-aggregation. While the description of FIGS. 2-3 may be made with reference to other figures, it should be understood that the exemplary processes illustrated in FIGS. 2-3 are not intended to be limited to being associated with the systems or other contents of any specific figure or figures. Additionally, it should be understood that while the exemplary processes of FIGS. 2-3 indicate a particular order of operation execution, in one or more alternative implementations, the operations may be ordered differently. Furthermore, some of the steps and data illustrated in the exemplary processes of FIGS. 2-3 may not be necessary and may be omitted in some implementations. Finally, while the exemplary processes of FIGS. 2-3 contains multiple discrete steps, it should be recognized that in some environments some of these operations may be combined and executed at the same time.

FIG. 2 is a flow diagram illustrating an exemplary process for sectioning and re-aggregating a document. At 210, a first version of a document is divided into one or more sections. These sections may correspond to headers, paragraphs, pages, or any other units or items in the document. At 220, formatting may be removed from one or more of the sections. For example, special fonts, paragraph formatting, or other formatting in the document may be removed. At 230, a condensed version of the document is generated. The condensed version of the document includes one or more links corresponding to the one or more sections. A link may specify one or more words in the corresponding section. The one or more links may include a link to a table, graph, image, audio, or video. A link may also specify the file size of the corresponding section or linked item. At 240, the condensed version of the document may be transmitted to a mobile device. The mobile device may process the document and display the document for a user. The user may select to download one or more of the sections. Once the full text of a section has been downloaded, the user may read and/or edit the section. The user may then choose to send back a modified version of the document. At 250, a modified version of the document may be received from the mobile device. Each section of the modified version of the document received from the mobile device may be compared with each section of the first version of the document to determine whether there are any changes. If a section has been changed, the modified version of the section may be used to replace the first version of the section. After each section has been compared and any modified sections replaced, then at 260, the sections are re-aggregated to form a revised document. The formatting that was removed at step 220 may be added back into the revised document. The revised document may then be displayed for the creator of the first version of the document.

FIG. 3 is a flow diagram illustrating an exemplary process for displaying and modifying a sectioned document. At 310, a condensed document is received at a mobile device. The condensed document may include one or more links to one or more sections and/or one or more downloadable items. At 320, the condensed document is displayed for a user. A user may select to download one or more of the sections or items by selecting the corresponding link. At 330, the user's request to download one or more of the sections or items is received by the mobile device. At 340, the requested one or more sections or items are downloaded and displayed for the user. The user may modify a downloaded section. For example, the user may use Microsoft® Office for Windows® Mobile to read and modify a downloaded section. At 350, the downloaded section is modified in response to user edits. At 360, the modified section may be transmitted to a computing device. The modified section may be re-aggregated with the unmodified sections to form a revised document. The revised document may then be displayed for the creator of the original document.

FIG. 4 is a screenshot of an exemplary document 400. The exemplary document 400 includes a number of headers, such as Lorem ipsum, Ut wisi, Duis autem vel eum, and Nam liber tempor. The headers are also listed on a Table of Contents at the beginning of the document. The document 400 may be divided into sections based on the headers in the document. For example, section 402 includes the text under the header “Lorem ipsum”, section 404 includes the text under the header “Ut wisi”, section 406 includes the text under the header “Duis autem vel eum”, and section 408 includes the text under the header “Nam liber tempor”. A condensed document may then be generated that includes a link to each section. The condensed document may then be transmitted to a mobile device and displayed for a user as shown in FIG. 5.

FIG. 5 is a screenshot of an exemplary condensed document 500 displayed on a mobile device. Each link included in the condensed document 500 corresponds to a section of the document 400 shown in FIG. 4. Each link specifies the name of the header of the corresponding section. For example, link 502 specifies the header “Lorem ipsum”, which is the header of the corresponding section 402, link 504 specifies the header “Ut wisi”, which is the header of the corresponding section 404, link 506 specifies the header “Duis autem vel eum”, which is the header of the corresponding section 406, and link 508 specifies the header “Nam liber tempor”, which is the header of the corresponding section 408. Each link may also specify a page number of the corresponding section. For example, link 504 indicates that the section with the header “Ut wisi” starts on page 1 of the document and link 506 indicates that the section with the header “Duis autem veleum” starts on page 2 of the document when viewed on the mobile device.

A user may choose to download a section by selecting the corresponding link. The user may also choose to download multiple sections or to download the entire document. The selected one or more sections are then downloaded and the full text of each selected section is displayed for the user. For example, if the user selects link 502, then section 402 of document 400 would be downloaded, and the full text of section 402 would be displayed as follows: “Dolor sit amet, consectetuer adipiscing elit, sed diam nonummy nibh euismod tincidunt ut laoreet dolore magna aliquam erat volutpat.” Once a section is downloaded, the user may read and edit the section. The user may then choose to send the revised section to the creator of the original document.

FIG. 6 is a screenshot of an exemplary document 600. Document 600 includes a FIG. 602. Document 600 may be divided based on the headings, such as “DUIS AUTEM VEL” and “DOLORE MAGNA ALIQUAM ERAT.” A condensed document may be generated that has a link to each of the headings and a link to the figure. Alternatively, since this document is short, the condensed document may contain the full text of the document with a link to the figure. The condensed document may be sent to a mobile device for display as shown in FIG. 7.

FIG. 7 is a screenshot of an exemplary condensed document 700 displayed on a mobile device. The condensed document 700 includes the full text of the document 600 shown in FIG. 6 and a link 702 to the FIG. 602. A user may scroll from one page to the next to read and/or edit the document. To look at the figure, the user may select the link 702 entitled “FIG. 1: Loren & Ipsum (38 k).” The link 702 specifies the size of the FIG. 602 (38 k) to let the user know approximately how big the figure is and how long it might take to download the figure. When the user selects link 702, the FIG. 602 is downloaded and then displayed on the mobile device for the user. If the user modifies the document, the user may then send the modified document to the creator of the original document.

FIG. 8 is a screenshot of an exemplary presentation document 800. A condensed document may be generated that includes the title 802, bullet points 804, 806, 808, 810, and 812, and a link to the FIG. 814. This condensed document may then be transmitted to a mobile device for display as shown in FIG. 9.

FIG. 9 is a screenshot of an exemplary condensed presentation document 900 displayed on a mobile device. The condensed presentation document 900 includes a title and bullet points that correspond to the title and bullet points in presentation document 800 shown in FIG. 8. For example, title 902 corresponds to title 802, and bullet points 904, 906, 908, 910, and 912 correspond to bullet points 804, 806, 808, 810, and 812, respectively. The condensed document 900 also includes a link 914 to FIG. 814. A user may choose to download the FIG. 814 by selecting the link 914, which is entitled “FIG. 1: Lorem & Ipsum (38 k).
